Our technology helps you achieve ultra-low carbon, nitrogen, and hydrogen contents. Used as a reaction gas, CO2 has a strong cooling effect in vacuum decarburization. This means you save on metallic coolants when treating ferrochrome and ferromanganese. You also consume less argon. The entire process engineering ensures lowest operating costs.

These are your benefits from two-stage decarburization in our vacuum converter:

AOD process at ambient pressure for medium-carbon grades

Decarburization and degassing under vacuum for steel grades and ferroalloys with low and ultra-low carbon and nitrogen contents

The dedusting hood for AOD operation and the vacuum cover for vacuum operation are installed on a sliding car. That makes it easy to move them between the two treatment steps.
